HERMAN A. BRANDENBURGER, F LOUIS, MISSOURI.

Application filed July 24, 1911.

I To all whom it may concern:

Be it known that I, HERMAN A. Bnannm siding atthe city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Tires, of which the following is a specification.

. The present invention has reference to protective armor for automobile tires, anal it comprehentls certain improvements in tire armor of the type shown and described in my prior application, Serial .No. (32.,

filed May 27, 1911. These improvements 1i}:-

late primarily to the filling (liSkS which are inserted in the interstices of the metal fabric constituting the body of the armor, ktlltl they consist in constructing the aforesaid tllsks in such a manner as to incriaise the j flexibility of the armor and to enable it. to

lmore readily shape itself to the contour of lthe the l A structural embodiment. of the invent on is illustrated in the accompanying draw ings, wherein:

Figure 1 is a transverse sectional view of an automobile wheel equipped with a tire constructed in accordance with saicl ini'en' tion; Fig. 2 is an enlarged section taken on the line Q' 2 of Fig. 1; Fig. 25 is a plan View 3 of a portion of the fabric; Fig. 4- is a s t: tion taken on the line 4 4.- of Fig. l ir 's. 5 and 6 are, respectively, a plan view anti :1 side elevation of one of the filling piece that are employed in the tread portion of the armor.

As shown in said drawings, the fabric proper 1 is composed of series of rows of rings 2 connected or interwoven together in much the same manner as the rings of a soicalled coat of chain mail. The fabric is il the form of a. continuous hand which, in the construction illustrated, is embedded in the body of the tire proper 3 (luring the making thereof, and may be connected to the folly ,4 of the wheel in any suitabh manner, such, for instance, as that shown and described in my prior appli ation above identified.

The interstices between matually alljzwent rings are designed to receive filling pieces, which latter are preferably two hintls as depicted in Fig. 3. The filling pier-es 5 that are arranged in the tread portion of the tire are shown in tletail in Figs. anti 8.

They consist of disks 6 having cona'ex outer faces and flat or plane inner faces, and are Specification of Letters Yatent.

The completed fabric, as will be uniler stood from the loiegoing is of tubular conformation when completed. the inner ethics oi" the i'ahric being loll tletarht-al, however, until both sides of saitl fabric are (over ell with rubber, after which "will edges are couuectetl to each other and .lie joint then \'ulcanizetl. 'l 3 tire thus formed will he stiengiheneu to a great r-Xmul. ivy the our huhlerl fabric and es; e .iall at its treatl portion, by reasn of the extension of the projections oi' the filling piece-s 5 to the surface of that portion. The employment. of the filling pieces results in the formation of a practically continuous metal fabric, as will be mule ootl; and by utilizing the piano-convert disks above described. the liexi hility oi the fabric is materially increased, since the fahric is allowetl more easily to shape itself to the contour of the tire.

Inasmuch as he rubber runs int anti fills the interstices in the (.llt''illzllltifllbl armor of this construction, it do in the Ihairrantl-(li l- U copcn-ilii application, Serial No. 625,836, filed iii 2?, i911, the rubber so amelgaiuates will the clmin-antlalisk armor to form much an integral fabric as is rubber-soaked care yes or other reticulated i'naterial. Due to the disks helcl be PPR the rings at chain work, the rui i is nit intimately a sociaietl with ill parts of the metal worn, due to the t; that it The pieces 3 along y or lOL tions or the fabric at by planoronrex to the dish PUi'lb runs into all the interstices of same while it. is in a molten condition. The Ci'lililhfiilfidisk rubber fabric thus formed possesses the qualities of flexibility and impenetrability that render same particularlywe}! adapted fer automobile tires.

\Vhat is claimed is:

1. Protective armor for tires comprising a band of chain fabric and filting disks inserted Wholly in the interstices thereof, said disks having their outer sides convex and their inner sides fiat.

2. Proteetivesarmor for tires cemprising a continuous tubular band of chain fabric having its side edges connected together and piano-convex filling disks inserted Wholly in the interstices of said band.

8. A fabric comprising 21v body of 'tUbbQf and a band embedded therein and c0nsi.t-- ing of interwoven rings having pizmdeon vex iiiiing disks inserted in the interstices therebetween.
